2008 Exam Question 78: In pond water, the duckweed population grows at an average rate of c 1 plant per 3 days

The point on the solid black line representing growth with N-P-K solution after fifteen days is higher on the y-axis, which represents number of plants, than the same x-coordinate in other lines. 2008 Exam Question 79: Duckweed vegetatively reproduced at the fastest rate in e) N-P-K fertilizer solu

    1. 2008 Exam Question 78: In pond water, the duckweed population grows at an average rate of c) 1 plant per 3 days

    2. 2008 Exam Question 79: Duckweed vegetatively reproduced at the fastest rate in e) N-P-K fertilizer solution

    18. Question 95: In which region of the curve is population size most likely to exhibit regulation by availability of resources such as nutrients, nest sites, and places to hide from predators? e) III and IV

    19. Question 96: Which of the following is the most appropriate method to prepare a sample of cheek cells for PCR? a) Obtain cells with saline mouthwash, boil, and chelate out any contaminating metals

    20. Question 97: In order to amplify the sequence with part of the TAS2R38 gene, which of the following would be the appropriate primers to use? b) Primers that correspond to the 5 and 3 ends of the sequence near the SNP sites

    21. Question 98: Why does digesting the DNA with enzyme X enable a prediction of the cell donors ability to taste? a) The nontaster allele (t) will not be cut and will therefore generate a larger fragment

    22. Question 99: Following the amplification and restriction enzyme digestion, the presence of the T allele is recognized on the electrophoresis gel by two bands: one of 177 base pairs (bp) and another of 44 bp. The heterozygote(Tt) will show three bands on the gel. Which of the following describes their sizes? d) 44, 177, and 221

    23. Question 100: The students further studied DNA sequence data from various primates in order to explore the evolution of this gene sequence. The study revealed that each of the other primates has the same SNP pattern as human tasters. Which of the following is the most reasonable inference that can be made about the evolution of this gene sequence? e) The ability to detect bitter taste must have some selection advantages for nonhuman primates
